The Grabarchuk family-father and sons-make some
of the most original and ingenious brain teasers in the world. I could
happily spend weeks with this book.

The talented Grabarchuk family have produced a
tantalizing collection of highly original puzzles, each with its own
set of rules (or rules you have to find yourself). Often geometrical
in character, these puzzles are always entertaining and sometimes
fiendishly difficult. The sudoku player in the airplane seat next to
you will be green with envy!

An excellent collection of 108 puzzles from an
Eastern European perspective, a counterpart to the Oriental flavor of
Nob Yoshigahara's Puzzles 101.
